CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 302,892, dated August5, 1884.

Application filed December 19, 1883. (No model.)

This invention relates to certain new and useful improvements in theconstruction and operation of car-couplings of that class wherein theordinary link and pin are employed.

The invention consists in the peculiar con-,

struction, combination, and operation of the parts, by means of whichthe pin is supported during the withdrawal of the link in the initiatorypart of such movement, and the completion of such withdrawal changes theposition of the pin ready to engage with the entering-link in theoperation of recoupling, as more fully hereinafter described.

Figure 1 is a vertical central longitudinal section through the centerof the draw-head, with all the other parts removed. Fig. 2 is a likesection with the parts all in place, as when the coupling is completed.Fig. 3 is a like section showing the position of the parts, the shuttlesupporting the pin preparatory to the removal of the link. Fig. 4c is alike view showing the change in the position of the pin and the mannerin which the shuttle supports the same, and the link entering to engagewith the pin by forcing the shuttle into the position shown in Fig. 2,whereby the pin is allowed to drop into its engagement.

In the accompanying drawings, which form a part of this specification, Arepresents a draw-head, with bell-mouth B leading into a chamber, 0, andprovided with a vertical hole through the center of the device,to allowthe pin D to pass. The upper part of this chamber 0 is in line with theupper wall of the bell-mouth B, and the chamber is pro vided with arecess, b, and a guideway, c, is formed in the rear wall of saidchamber.

E is a shuttle, a perspective view of which is shown detached from theother parts, and upon its rear face is a guide-flange, d,

which slides in the guideway. The upper portion of this shuttle or stopis made heavier than the lower portion thereof, and in the front facethere is formed a semicircular recess, which, when the pin is insertedthrough the draw-head, is coincident with the pin-hole therein, thelower edge of said shuttle resting upon the link F. In the withdrawal ofthe pin, the upper portion of this shuttle, being heavier than the lowerside thereof, falls for ward into the recess 1), therebyv presenting anobstruction to the pin dropping back into its seat, and leaving the linkin position to be withdrawn. As the link is withdrawn the shuttle dropsa little upon a radial movement until the upper end of the recesstherein is presented coincident with the upper pin-hole, and the lowerportion partially covers the entrance to the bottom pinhole, when thepin drops into such recess as the link is withdrawn and holds theshutter in this position, while at the same time the latter prevents thepin from dropping into the lower pin-hole. In this position the deviceis ready to receive the entering link, which, striking the lower side ofthe shuttle, forces it into an upright position, disclosing the lowerpin-hole and allowing the pin to drop into its proper engagement.

It will be noticed that the principal part of my invention is in ashuttle adapted, in the movements of coupling and uncoupling, to havetwo movements, the first being that the upper and heavier portion fallsforward,upon the pin being withdrawn. to form a rest for the end of thepin, and the other to recede from this position, and the lower edgeradially drawn forward by the withdrawal of the link, and partiallycovering the lower pin-hole, allowing the pin to drop into the re cessin the shuttle, and by such movement wedging the shuttle and pin in thechamber until the entering link, striking the lower edge of the shuttle,drives it from its last position radially to the rear, whereby itsrecess is presented in coincidence with both the upper and lowerpinholes, so that the pin may fall unobstructedly.

WVhat I claim as my invention is 1. In combination with a draw-head,ashuttle inclosed in a chamber therein, and provided with a recess in itsfront face, and havcidentgwhen the pin and link are in p1ace,with ingthe two movements under the operationof the pin-hole a, the partsconstructed and 0pthe pin and link herein described, and for the eratingsubstantially as specified.

purposes set forth. OROWELL M. OLANOY.
